Hi guys, recently purchased a used g37x and today i decided to buy new engine filters for the car and chose the k&n filters. However, upon installing them i find these filters were hard to lock in and required much more force than the paper filters to lock in place. Is the extra force a sign that these filters have problems or is it normal?

 

It's perfectly normal. I have them as well and it took some force to get it to clap together. No worries though

 

how long have you had the filters for and did you have any problem with the MAF?

 

+1

I prefer afe dry filters. Same price, reusable, and no worries about the oil messing with the MAF.

 

I have had them in for a month and have no codes.

 

Yup, i think i had the problem too but was able to put it in.. darnn..it has been about 13,000 miles now & haven't cleaned it... come on Fall weather!!

 

I've installed mined 3 weeks after i bought this car and I put 85k miles on them with no issues.
